删除单行数据

前提条件

初始化Tablestore Client

方法说明

func (tableStoreClient *TableStoreClient) DeleteRow(request *DeleteRowRequest) (*DeleteRowResponse, error)

示例代码

以下示例代码用于删除 test_table 表中主键值为 row1 的行数据。

func DeleteRowSample(client *tablestore.TableStoreClient) {
    // 构造主键
    deletePk := new(tablestore.PrimaryKey)
    deletePk.AddPrimaryKeyColumn("id", "row1")

    // 构造删除的行数据
    deleteRowChange := new(tablestore.DeleteRowChange)
    deleteRowChange.TableName = "test_table"
    deleteRowChange.PrimaryKey = deletePk 
    // 删除行数据时必须配置删除条件 （RowExistenceExpectation_IGNORE，表示不做行存在性判断）
    deleteRowChange.SetCondition(tablestore.RowExistenceExpectation_IGNORE)

    // 调用 DeleteRow 方法删除行数据
    deleteRowReq := new(tablestore.DeleteRowRequest)
    deleteRowReq.DeleteRowChange = deleteRowChange
    response, err := client.DeleteRow(deleteRowReq)
    if err != nil {
        fmt.Println("Delete row failed with error: ", err)
    } else {
        fmt.Printf("RequestId: %s \n", response.RequestId)
        fmt.Printf("Read CU Cost: %d \n", response.ConsumedCapacityUnit.Read)
        fmt.Printf("Write CU Cost: %d \n", response.ConsumedCapacityUnit.Write)
    }
}
